Graphene Explained: A Beginner's Guide to its Properties
Graphene has emerged as one of the most promising nanomaterials because of its unique combination of exceptional properties: it is not only the thinnest but also one of the strongest materials; it conducts heat better than all other materials; it is an excellent conductor of electricity; it is optically transparent, yet so dense that it is impermeable to gases – …
MXene - what is it, how it is made, what it is used for - Nanowerk
MXenes are ceramics that comprise one of the largest families of two-dimensional materials. MXenes are made from a bulk crystal called MAX. Unlike most 2D ceramics, MXenes have inherently good conductivity because they are molecular sheets made from the carbides and nitrides of transition metals like titanium.
Nanorods: Elongated Nanostructures with Unique Properties
Nanorods are elongated nanostructures with a diameter in the nanometer range and an aspect ratio (length-to-width ratio) greater than one. They are typically characterized by their unique optical, electrical, and magnetic properties that arise from their anisotropic shape and quantum confinement effects.
What are nanobots? Explaining nanorobotics and nanorobots
A nanobot, also known as a nanorobot, is a term used to describe a molecule that has the capability to be programmed to perform a specific task. The field of nanorobotics involves the creation, production, programming, and control of robots that operate at the nanoscale.
MOF Metal Organic Framework - definition, fabrication and use
Metal-organic frameworks (MOFs) are organic-inorganic hybrid crystalline porous materials that consist of a regular array of positively charged metal ions surrounded by organic 'linker' molecules. The metal ions form nodes that bind the arms of the linkers together to form a repeating, cage-like ...
